The social structure and genetic make-up of the hoary bat (Lasiurus cinereus) during its fall migration is not well known. Recently, pairs of male hoary bats were observed flying together in the Humboldt Redwoods during the autumn migration. When one individual was netted, the other member of the pair circled around and remained in the area while the two bats called to one another. This suggests a strong social, and a possible genetic, bond between the two males. In order to determine whether these males were related, wing tissue samples were collected from 15 pairs and 76 singleton individuals from …

We developed eight polymorphic microsatellites from the parasitic nematode Baylisascaris procyonis. Amplification of these loci in a sample of 74 worms collected from 10 raccoons in Western Michigan revealed significant population structure. Bayesian clustering indicates two subpopulations, one on either side of the Grand River which bisects the region sampled. Estimates of FST, and results from AMOVA and isolation by distance, further corroborate a scenario whereby the river is acting as a barrier to gene flow, a rather unusual finding given the high vagility of raccoons and microgeographic scale of the analysis. We describe one possible mechanism …
